Global warming today could have similar effects on ocean currents and could accelerate climate change The Atlantic Ocean circulation (termed meridional overturning circulation, MOC) is an important component of the climate system. Warm currents, such as the Gulf Stream, transport energy from the tropics to the subpolar North Atlantic and influence regional weather and climate patterns. Once they arrive in the North the currents cool, their waters sink and with them they transfer carbon from...

Boulders deposited by an ancient glacier that once covered the summit of Mauna Kea on the island of Hawaii have provided more evidence of the extraordinary power and reach of global  change, particularly the slowdown of a North Atlantic Ocean current system that could happen again and continues to be a concern to climate scientists. A new study has found geochemical clues near the summit of Mauna Kea that tell a story of ancient glacier formation, the influence of the most recent ice...

A team of scientists has returned to the North Atlantic to gather more data on the Icelandic volcanic eruption that took place earlier this year. The researchers are studying whether iron within the vast volcanic ash cloud entered the ocean, causing an extended bloom of tiny organisms known as phytoplankton. The scientists have recorded "enhanced levels" of iron in samples they have collected. The most recent project follows an earlier cruise, which was carried out in the spring. The...

North Pacific circulation radically changed by past post-glacial warming Toward the end of the last ice age, a major reorganization took place in the current system of the North Pacific with far-reaching implications for climate, according to a new study published in the July 9, 2010, issue of Science by an international team of scientists from Japan, Hawaii, and Belgium. Earth's climate is regulated largely by the world ocean's density-driven circulation, which brings warm surface water to...

Just like people in a bar or other noisy location, North American right whales increase the volume of their calls as environmental noise increases; and just like humans, at a certain point, it may become too costly to continue to shout, according to marine and acoustic scientists. "The impacts of increases in ocean noise from human activities are a concern for the conservation of marine animals like right whales," said Susan Parks, assistant professor of acoustics and research associate,...

A chain of past natural events may hold lessons for the future Scientists still puzzle over how Earth emerged from its last ice age, an event that ushered in a warmer climate and the birth of human civilization. In the geological blink of an eye, ice sheets in the northern hemisphere began to collapse and warming spread quickly to the south. Most scientists say that the trigger, at least initially, was an orbital shift that caused more sunlight to fall across Earth's northern half. But how...

According to four French explorers just back from eight months at sea, the North Atlantic Ocean is looking more like a rubbish bin, with plastic and polystyrene flotsam spreading far and wide. The researchers found at least four to five pieces of trash a day once out of the Britanny port of Trinite-sur-Mer in October.  In April they found a floating dump in the Sargasso Sea around Bermuda. "In 15 minutes we saw more garbage than at any time during our journey," naval engineer Yann...

Inputs of dust from the Sahara desert could change the composition of microbial communities in the (sub)tropical eastern North Atlantic say Southampton researchers writing this month in the journal FEMS Microbiology Letters. When high winds blow over the Sahara, dust particles consisting of soil particles are lifted high into the atmosphere, blown over the sea, and then deposited on the ocean surface. "Desert dust particles contain nutrients such as iron that can boost the production of tiny...

A team of researchers from the UK's National Oceanography Centre will be spending the next month investigating how recent eruptions of an Icelandic volcano have effected marine life in the North Atlantic, according to a Thursday BBC News report. Earlier this month, eruptions at a volcano located beneath the Eyjafjallajokull glacier in southern Iceland covered the area with volcanic dust and created an ash cloud that crippled European air travel for the better part of a week. Now, the research...

The main cause of a rapid global cooling period, known as the Big Freeze or Younger Dryas - which occurred nearly 13,000 years ago - has been identified thanks to the help of an academic at the University of Sheffield. A new paper, to be published in Nature on April 1, 2010, has identified a mega-flood path across North America which channeled melt-water from a giant ice sheet into the oceans and triggering the Younger Dryas cold snap. The research team, which included Dr Mark Bateman from...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

The North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...

The Humpback Whale (Megaptera novaeangliae) is a mammal, which belongs to the baleen whale suborder. It is a large whale: an adult usually ranges between 40"“50 ft (12"“16 m) long and weighs approximately 79,000 pounds (36,000 kilograms, or 36 tons. It is well known for its breaching (leaping out of the water) and its unusually long front fins. The Humpback Whale lives in oceans and seas around the world, and is regularly sought out by whale-watchers. Feeding The Humpback Whale...
